Hi I have a combobox with items {item1,item2,item3...}
Each of these items should fill a groupbox{textbox1,textbox2,textbox3}with different parameters.
My idea is to create a different class {classitem1 classitem2} where to declare all the methods for filling the groupbox with parameters but being a beginner programmer not quite sure about how to do this.
any help please

Sorry this is Windows Forms.
The problem for me is how to refer to values of textboxes from the class For example if I create

class 1 
{ 
public void fillGroupBox() 
{ 
//how to refer to form1.txtbox? 
}

Tag it? WPF, Forms, APS.NET, what?!
What seems to be a problem? What did you try? This is right idea, just do it.

Solution 2

public class MyClass
{


    /* For Load Data, Return as a Dataset */
    public DataSet FillData(Pass_your_Values)
    {
// COde for fillup.
    }
.......
.....

And you can bind these dataset or daatable item into combobox.
